Definitely not. The Art of Software Testing wrote about "module testing" in 1979, which was revised as "unit testing" in a later revision after "unit test" was part of the popular lexicon. Perhaps that is what you are thinking of?

Beck is clear that he "rediscovered" the idea. People most certainly understood the importance of tests being isolated from each other in the 1960s. Is that, maybe, what you mean?

Quote:

"Unit test:

testing, outside of thesystem, of a part of the system thatmay have less than a complete function.

Component test:

testing, inside of the system, of parts that have been successfully unit tested.

Integration test: testing of new components to ensure that the system is growing functionally; in addition, retesting of successive system builds to ensure that they do not cause re-gression in the capabilities of the system.

Regression test: testing of the system for unpredictable system failure.

Scaffolding:

coding that replaces not - yet - completed functions..."

I was taught in the 80's about this by a woman that had worked at some company that was more formal about software dev than we were at the small company I worked for.
